which gas? what density, temperature etc.

many people have simulated noble gases. a code (and inputs)
for simulating argon is bundled with and explained in most
introductions on classical MD. just pick up a text book on MD.
building a topology for a noble gas is trivial, since there
are no bonds, angles, dihedrals etc.

cheers,
